Abstract: PCT No. PCT/GB90/00837 Sec. 371 Date Jan. 27, 1992 Sec. 102(e) Date Jan. 27, 1992 PCT Filed May 30, 1990 PCT Pub. No. WO90/15092 PCT Pub. Date Dec. 13, 1990.This invention relates to the production of hydroxy-terminated polymers in the 2,000-20,000 MW range suitable for use as prepolymers in curing reactions with isocyanates to produce elastomers. The process involves the continuous addition over periods of 25-50 hours of an oxirane (monoepoxide) or a mixture of an oxirane and an oxetane to a reaction mixture, consisting of stoichiometric excesses of oxonium ion-forming catalyst such as BF3-etherate and a diol initiator dissolved in an inert solvent. Under these conditions, chain extension of the diol occurs and the formation of cyclic oligomers and other impurities is minimised. The mole ratio of the initiator to catalyst is maintained at above 10:1 to suppress the formation of cationic terminal species on the growing polymer chain.

Abstract: Transport plate (28) is moved downwardly into engagement with work product (25) and the plate (28) moves the work product to the edge finisher, such as sewing head (12) (FIG. 3). When the first edge (68) covers the first sensor (61), the transport plate (28) begins its movement from right to left (FIG. 4) so as to move the first edge (28) through the edge finisher, and the edge is finished as with an overedge stitch. When the second edge (69) uncovers the second sensor (62), the transport plate (28) rotates around an axis of rotation (75) (FIG. 5), causing the work product (25) to be rotated about the same axis of rotation (75) and the edge finisher forms the overedge stitch about the curved path until the second edge (69) covers first sensor (61), whereupon the linear right to left movement is resumed (FIG. 7).

Abstract: A turbomolecular pump comprising, in addition to usual axial flow pumping stages consisting of alternated rotors (1,1a) and stators (2,2a), one or more tangential flow pumping stages (10;30) arranged at the exhaust side of the pump, to raise up the compression ratio. Each axial flow stage consists of a plane disk rotor (12;35) encompassed to a coplanar annular stator (13;36), spaced apart from the rotor disk, so that a free annular channel is formed in-between (14;38), in which channel the pumped gases move along a tangential flow. Such channel is closed by a baffle (15;39), and communicates with a suction port (17;40) and a discharge port (18;41). The plane disk rotor may be provided of vanes (37,37a,37b). It is possible to combine tangential flow stages (10) having rotor without vanes (12) and tangential flow stages (30) having rotor with vanes (35); in such a way it is possible to raise the exhaust pressure up to the atmospheric pressure, and to discharge directly in the atmosphere. <IMAGE>

Abstract: In a coder frames of a digital video signal are scanned to get blocks of pixels, motion vectors are estimated and block errors are calculated using the decoded foregoing frame, thereby providing an intra/inter decision signal and intraframe-blocks of pixel values or motion compensated interframe-blocks of pixel difference values depending on the result of the block error. The blocks of pixel values and pixel difference values, respectively, are transformed with a DCT to blocks of coefficients, coded together with the motion vectors in a Huffman coder with variable word length. The resulting groups of coded coefficients are quantized individually by the use of a quantization level and the coded coefficients of the group are individually quantized by the use of a quantization matrix, controlled by the fullness of a buffer. In decoder groups of coded coefficients which belong to blocks of pixels are de-quantized individually by the use of an encoding quantization level and each coded coefficient of each group is de-quantized individually by the inverse use of an encoding quantization matrix, controlled by the fullness of a buffer. The groups of coded coefficients and motion vectors are decoded in a Huffman decoder with variable wordlength, thereby providing blocks of decoded coefficients. The blocks of decoded coefficients are transformed with an inverse DCT to pixel values and pixel difference values, respectively, out of which blocks of pixels out of intraframe-blocks of pixel values and motion compensated interframe-blocks of pixel difference values, respectively, are generated depending on an intra/inter decision signal, thereby evaluating the motion vectors. The blocks of pixels are filtered at their boundaries, if the according adjacent block has not nearly the same motion vector, and are inserted again in frames of a digital video signal in an according order. The decoded blocks of coefficients are filtered in both, coder and decoder. The visibility of coding artefacts is thereby reduced.

Abstract: An apparatus for developing an image on a photoconductive surface (34,44). The apparatus includes a first roller (36) positioned adjacent to the photoconductive surface (34). Negatively charged toner is supplied to the surface of the first roller (36) where the toner electrostatically adheres, either in a uniform layer or a variable layer, to the surface of the first roller. The negatively charged toner electrostatically adhered to the surface of the first roller (36) is then transferred to the photoconductive surface (44). The apparatus may also include a second roller (38) held at a positive charge relative to the first roller (36) for electrostatically transferring toner from the second roller to the first roller. Alternately, the positive charge on the second roller relative to the first roller may be produced by placing a negative charge on the first roller or by placing a negative charge on the second roller and a more negative charge on the second roller. By placing a negative charge on the second roller, the toner will also be negatively charged before transfer to the first roller. <IMAGE>

Abstract: The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image are converted by a color correction computer into control signals representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles located on a pair of printheads. Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first source is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations. The present invention, additionally, is provided with heaters and a wiper arm and sponge which operate together to enhance adherence of ink onto the substrate.
